My version of PBR Material with glossy & specular fresnel Tweet

[noldo]

Hi, I would like to share with you, to test it, my personal version of PBR material.
The material include a sperimental glossy fresnel feature & specular fresnel power.
Every exposed value has a description and a default value.
I would like to receive criticism and corrections.
Sorry for my english, i'm italian!
Bye

For clarity, i suggest to modify the falloff glossiness value & falloff specular power, the other value only if you want to achieve a particular influence.
Obviously, the PBR texture gamma of all texture is 2.2, except for the roughness (if you have a glossy map, set the gamma to 1.0 and invert value).

Some testing with the free version of friendly shade texture.
